A potent cannibal solar storm has hit Earth and could put on a spectacular northern lights display across the U.S tonight.
A fast-moving coronal mass ejection (CME), launched by a long-duration M2.7 flare from sunspot AR 4199 on Aug. 30, slammed into Earth's magnetic field around 5 p.m. EDT (2100 GMT) on Sept. 1, according to NOAA's Space Weather Prediction Center (SWPC).
